Charlene:
I reviewed the weir equation shown on the plans and the height of flow over weir (H) should
have been raised to the 3/2 power as you surmised. I appreciate your thorough review and we
have revised the calculations. To insure the depth of flow does not exceed 6 inches, we have
revised the plans to indicate 3-6"x48" openings on each corner.
I have attached Adobe pdf files of the revised sheets for your review. If OK just let me know
how many copies you will need.
Thanks again
